If you find it difficult to develop it, it’s ok. The inventor inscribed a shield for Arduino, which he developed in Cadsoft EAGLE. It is rather powerful to control the axis of this DLP 3D printer. The new 3D printer is controlled by Arduino UNO. That’s why he tried another toy, which can help build lightweight large strong constructions, possessing the same flexibility for changing the design as the LEGOs do. They can be efficient, but the interlocking bricks aren’t suitable for stable large constructions. He explained that LEGOs aren’t stable enough. You’re probable interested why the student didn’t use just LEGOs. Is there anything cheaper? In addition, you can use literally anything as a resin tank, provided it is leak free and waterproof, a bit larger than the build side and doesn’t dissolve contacting the resin.Īll this is carried inside a simple nice looking body, which is a combination of K’nex and LEGOs. A simple sick aluminum sheet (taken from the back part of the LCD screen) makes up the build platform. The Z axis is made up of a laser deck assembly of a computer disk drive, which is not unusual for homemade 3D printers. Be cautious so as not to blind yourself and follow the tutorial. It’s easy to get the resin cured quickly – you just have to remove the filter in the front part. To make it perfect for additive manufacturing, key removes the UV filter and modifies the close distances. The student used a Mitsubishi XD221u projector having a 1024×768-pixel resolution, so this area in the guideline. Check if it is with a suitable high resolution. ![]() Make sure you are buying a DLP projector not a LCD machine. In fact any DLP projector can perform well if you remember some things while choosing it. Some of them are labeled as used with 3D printers – like the Dell 2300, 2400, the Infocus 2104. ![]() On the market there are numerous projectors available nowadays. The most essential part is the projector. However you’ve probably guessed that there are some parts missing – computer disc drive laser deck with stepper motor, an Easydriver v.4.4, a DLP projector, the cheaper Arduino UNO, wires and some tools and the possibility to build a circuit board. Beware that UV light may cause burns and blindness, be very careful! If you are determined to try, you will find the tutorial on the Instructables. Just bear in mind that this machine is not so easy to build. If you would like to try and build the cheapest DLP 3D printer, here is an opportunity. Moreover the student-prodigy decided to share the designs with the public and provide a detailed manual that can be found at Instructables. The unique name Chimera is connected with a mythological creature that consists of three creatures – and the printer is made up of some firmware, toys and a projector. There is nothing wrong with the temperature of the extruder as there is no extruder. They don’t use a heated or exclusively flat bed. In top down DLP 3D printers of a simple form have just one moving axis – a video projector – and a small amount of electronics. Why is it so cheap to build it? That is mainly because top down DLP 3D printers that possess a resin tank over the building platform possess fewer moving parts. Finally he had everything to build a well-functioning 3D printer at a suitable price, which can create objects of high quality at less than a hundred dollars. He had partially completed three different 3D printers, but then he got to know DLP stereolithography 3D printers. ![]() In one of his interviews the student explained that he had been looking for a simple and cheap, yet high resolution machine for years. It’s better to call this printer a DLP 3D printer, but not a SLA 3D printer. The Chimera 3D printer can suggest you all this. ![]() A reliable one will cost you about $50-60. DLP projectors can do the same for some part of the price. Luckily SLA 3d printers are not just for commercial use to provide UV light. To make it clear, stereolithography (or SLA printing) relies on UV lighting for hardening liquid resin. His effort resulted in a nice-looking SLA 3D printer that can perform excellent work. Apart from them, he used K’nex and Lego parts. One of the Instructables users (matstermind, a young student from Indiana) has succeeded in it. However, there is another option – you can develop a machine yourself. Those who are willing to get machines capable of printing objects of high resolution have to pay thousands of dollars to buy machines that are based on other technologies. In the last couple of years the prices of 3D printers have been steadily reduced, but their development has mainly concerned FDM 3D printers.
